One of the options for increasing the versatility of tractors is to use them as a part of a modular traction device (MTD). The model MTD-100 consists of a power-generator module and a technical module. The power-generator module is a tractor with a nominal traction force of 14–16 kN. The technical module is an additional axle with wheels driven by the power-generator module ground speed power take-off. For agricultural implements whose traction resistance does not exceed 16 kN, only the tractor is used. When the technical module is attached to it, the traction force of the entire MTD-100 increases. The MTD-100 makes it possible to tow implements with a traction resistance of up to 30 kN. Since the rear wheels of the power-generator module are connected by a locked drive to the wheels of the technical module, there is a kinematic discrepancy Kv between them. Our studies have established that the greater the Kv value, the greater is the inflation pressure of the tyres on the wheels of the MTD-100 power-generator and technical modules. If it is necessary to ballast the MTD-100 technical module, the inflation pressure of its tyres should be increased. This makes it possible to maintain the value of the kinematic discrepancy coefficient Kv unchanged. Replacement of the standard 16.9R38 tyres with15.5R38 tyres on the rear wheels of the power-generator module and the wheels of the technical module of the MTD-100 requires practically no adjustment to their inflation pressure.

为模块化牵引装置评估的驱动轮之间的运动学差异

增加拖拉机多功能性的一种选择是将它们用作模块化牵引装置 (MTD) 的一部分。MTD-100 型由发电机模块和技术模块组成。发电机模块是一台额定牵引力为 14-16 kN 的拖拉机。技术模块是带有轮子的附加车桥，由发电机模块地速取力器驱动。对于牵引阻力不超过 16 kN 的农具，仅使用拖拉机。当技术模块连接到它时，整个 MTD-100 的牵引力增加。MTD-100 可以牵引牵引阻力高达 30 kN 的工具。由于发电机模块的后轮通过锁定驱动器连接到技术模块的轮子上，它们之间存在运动学差异 Kv。我们的研究表明，Kv 值越大，MTD-100 发电机和技术模块车轮上的轮胎充气压力就越大。如果需要对 MTD-100 技术模块进行压载，则应增加其轮胎的充气压力。这使得可以保持运动学差异系数 Kv 的值不变。将发电机模块后轮和 MTD-100 技术模块轮上的标准 16.9R38 轮胎更换为 15.5R38 轮胎几乎不需要调整它们的充气压力。MTD-100 发电机和技术模块车轮上的轮胎充气压力越大。如果需要对 MTD-100 技术模块进行压载，则应增加其轮胎的充气压力。这使得可以保持运动学差异系数 Kv 的值不变。将发电机模块后轮和 MTD-100 技术模块轮上的标准 16.9R38 轮胎更换为 15.5R38 轮胎几乎不需要调整它们的充气压力。MTD-100 发电机和技术模块车轮上的轮胎充气压力越大。如果需要对 MTD-100 技术模块进行压载，则应增加其轮胎的充气压力。这使得可以保持运动学差异系数 Kv 的值不变。将发电机模块后轮和 MTD-100 技术模块轮上的标准 16.9R38 轮胎更换为 15.5R38 轮胎几乎不需要调整它们的充气压力。
